Identification
Differs from M. plattei in larger somewhat rounder head; frontal costa strongly narrowed just above antennae; fastigium more strongly closed off and separate from frontal costa at front; tegmina with dark bands often tending to cross over top (reduced but usually present) as viewed with wings folded; inner face of hind femur usually pale to dark with two pale cross bands (usually dark with one pale cross band in M. plattei; and hind wing less consistently with a dark tip. These differences all tend to break down in southern Utah, but most populations can be called one or the other.
Range
Southwestern Utah, southern Nevada, and California south of Tahoe and east of Sierra Nevada.
Remarks
Probably a western variant of Mestobregma plattei with which it seems to intergrade in southern Utah.
